Excellent ED doublet refractor
I own this 102ED myself, and I am planning to add a mono camera and filters ouch instead of getting a triplet/APO
Suitable for beginner astrophotography
I purchased the 503 80ED last year after having entered into AP and had no idea what a doublet was. I found that the quality was great considering it was my first refractor.
The performance for visual astronomy has been great.
I bought the 102 version last month. I'm under Bortle 8 skies, so even my C6 has contrast issues . Yet, the Svbony, under full magnification 200x (using your favorite Baader Zoom and barlow set) at Jupiter and Saturn worked very well.

- 2. The objective lens features an S-FPL51 extra-low dispersion glass ED element, which eliminates chromatic aberration. This results in the best color correction for an ED doublet lens
- 3. The lens adopts optical processing and low polishing technology, which is carefully carved
- 4. The deceleration ratio of the two-speed 2'' toothed focusing seat is 1:10, which makes it easy to achieve accurate focus
